Princess Rosalinda (Demi Lovato) of the small nation of Costa Luna is about to be crowned queen. Inexplicably, General Kane (Johnny Ray Rodriguez), the dictator of a neighboring country (Costa Estrella), is able to infiltrate her palace with his agents during her coronation rehearsal, and attempts to assassinate her while effecting a coup d'etat against her regime. Luckily, Joe Mason, an agent of the Princess Protection Program, a secret organization funded by royal families that looks after endangered princesses, is able to whisk her away to safety via helicopter because Gen. Kane’s agents failed to secure the rooftop. They then succeeded in capturing her mother, Queen Sophia.To keep Princess Rosalinda hidden, the Princess Protection Program places her in Mr. Mason’s home in Louisiana because she refuses to trust anyone else. There she meets his daughter, Carter (Selena Gomez), an insecure girl who works at the local bait shop and dreams of going to the school dance with her crush, Donny (Robert Adamson). To become a normal teenager, Rosalinda takes the name Rosie and becomes popular at school, which Carter must learn to handle. The two become close friends. Carter then teaches Rosie to act like a normal girl and Rosie shows Carter how to disarm those that scorn them by behaving as a princess. Meanwhile, General Kane plots to marry Rosalinda’s mother, to legitimize his rule.

Joe Mason understands that if Rosie knows General Kane is forcing her mother, then she would want to give herself up in order to placate his need to secure his rule. He also knows that Gen. Kane is likely to simply kill Rosie if he can get the chance. Unfortunately, he did not anticipate the threat posed by the popular girls at school, who want Rosie to drop out of the Homecoming election. After discovering that Rosie is actually a princess, they tell Rosie about Gen. Kane’s plan and try to force her to drop out of the election by threatening to expose Rosie's identity, also destroying her and Carter’s homecoming dresses.
Rosalinda is distraught and decides to leave without anyone knowing besides Carter. She knows what will happen if Rosie returned, asking her to do her one last favor and stay until after Homecoming. Rosalinda agrees to wait until after the dance. To get new dresses, Carter calls Rosalinda’s dressmaker, Mr. Elegante, to send some as part of a plan to save Rosie. To carry out the plan, Mr. Elegante sends the dresses, and pretends to tell Rosalinda’s whereabouts to Gen. Kane to lure him to Louisiana (Carter's plan is to use herself as bait to get Gen. Kane to expose himself, knowing that her father "will always be there for [her]," and that there is no way a rogue dictator can land unnoticed by the authorities).

In the meantime, Rosie and Carter help a bunch of girls by dressing them up for the dance, which includes wearing masks to help Carter stand in for Rosie. Gen. Kane flies to Louisiana to attempt to abduct Rosie. Following her plan, Carter poses as Rosie by wearing a dress of the same color that Gen. Kane was told that Rosie would be wearing, and is taken to Gen. Kane's helicopter. Carter is saved by her father just in time.At the end, Carter realizes what a jerk Donny is and goes to the dance with Ed, who is her best friend and had a crush on her for a long time. Rosie is then crowned Queen of Costa Luna. Carter and Ed cheer, "Long Live Queen Rosie!", Rosie's mom says it in Spanish ("Viva la reina Rosalinda") and Rosie walks down the aisle with Carter smiling proudly
